Abstract
The invention discloses a sealing structure for a plug of an atmospheric side of an auxiliary shaft of an engine. A main oil hole (1a), an oil inlet hole (1b) and a plurality of oil outlet holes (1c) are arranged on the auxiliary shaft (1), the main oil hole (1a) is a step hole with two large ends and the small middle, the oil inlet hole (1b) is close to the atmospheric side of the auxiliary shaft (1), a step plug (2) is plugged at one end, which is close to the atmospheric side, of the main oil hole (1a), and consists of a guiding journal (2a), a sealing journal (2b), an annular groove (2c) and an end (2d) which are successively connected, and a sealing ring (3) is mounted in the annular groove (2c). The sealing structure resolves the technical problem of oil leakage of the plug of the atmospheric side of the auxiliary shaft of the engine, and has the advantages of simple structure, easiness in implementation and low cost.
Description
Technical field
The present invention relates to Motorcycle Engine Technology field, specifically, is a kind of sealing configuration that is used for preventing engine countershaft atmospheric side oil impregnate.
Background technique
As shown in Figure 4, the main oil-hole 1a of general motorcycle engine backshaft 1 adopts blind hole structure, and lubricant oil is from the oil-feed of main oil-hole right side, then flows into each oil outlet, for each gear rotary part being arranged on countershaft provides lubricant oil.Figure 5 shows that the engine countershaft structure of battery-operated motor cycle, the starting gear 5 that is arranged on main oil-hole 1a right side has taken the position of conventional oil inlet hole, need to be from the oil inlet hole 1b oil-feed of countershaft 1 left end, this situation adopts blind hole structure again, main oil-hole is by the deep hole becoming more than 150mm, and the coaxality requirement that general drilling machine does not reach φ 0.3, only has the deep hole drill of employing technology just can reach requirement, and deep hole drill technology not only needs to add deep-hole drilling machine, also high to skilled worker's requirement.General motorcycle engine backshaft processing factory does not also adopt the strength of deep hole drill technology.
The engine countershaft structure of starting gear is housed for right side, generally do not adopt blind hole structure, and main oil-hole is designed to through-hole form, as shown in Figure 3, main oil-hole 1a is designed to the step hole of big at both ends and small in middle, two ends all adopt Steel Spring Plate punching press plug 4 sealing, oil inlet hole 1b and some oil outlet 1c and vertical the communicating of main oil-hole 1a on countershaft 1.This plug is contained in engine interior, less demanding to the surface quality at main oil-hole 1a two ends, allows immersion oil; If be contained in atmospheric side, the surface quality at main oil-hole 1a two ends is had relatively high expectations, to Steel Spring Plate punching press plug 4 to press-fit required precision also very high, which not only processing cost is high, and oil impregnate problem can not be stopped completely.
Summary of the invention
The object of this invention is to provide a kind of sealing structure for plug of atmospheric side of auxiliary shaft of engine, reduce manufacturing cost, thoroughly solve the oil impregnate problem of countershaft atmospheric side plug.
For this reason, a kind of sealing structure for plug of atmospheric side of auxiliary shaft of engine provided by the present invention, on countershaft (1), have the main oil-hole (1a) axially running through, perpendicular to main oil-hole (1a) the oil inlet hole (1b) being communicated with main oil-hole (1a) and some oil outlets (1c), the step hole that described main oil-hole (1a) is big at both ends and small in middle, described oil inlet hole (1b) is near the atmospheric side of countershaft (1), key is: described main oil-hole (1a) is plugged with step plug (2) near one end of atmospheric side, described step plug (2) is by the guiding axle journal (2a) being connected successively, sealing axle journal (2b), circular groove (2c) and end (2d) form, described guiding axle journal (2a), sealing axle journal (2b) and circular groove (2c) arrange with one heart, described sealing axle journal (2b) and main oil-hole (1a) interference fit, guiding axle journal (2a) and main oil-hole (1a) Spielpassung, the diameter of described end (2d) is less than or equal to the diameter of sealing axle journal (2b), seal ring (3) is housed in circular groove (2c).
Guiding axle journal and main oil-hole Spielpassung, rise and press-fit leading role; The interference of sealing axle journal is fitted in the larger diameter end of main oil-hole near atmospheric side, and in conjunction with the seal ring assembling on circular groove, plays double seal.
Described main oil-hole (1a) is plugged with Steel Spring Plate punching press plug (4) away from one end of atmospheric side.Because main oil-hole is contained in engine interior away from one end of atmospheric side, less demanding to the surface quality in hole, allow micro-immersion oil, so Steel Spring Plate punching press plug just can meet seal request.
The end (2d) of described step plug (2) and sealing axle journal (2a) concentric settings, and end (2d) diameter is less than the diameter that seals axle journal (2b), to protect seal ring not press-fited damage, be easy to manufacturing, and total tune is attractive in appearance.
Be preferably, seal ring (3) is O-ring seals.
This invention has solved the technical problem of engine countershaft atmospheric side plug oil impregnate, has feature simple in structure, easy to implement, cost is low.
